Creating Custom Resources in Kubernetes 1 from Pluralsight

Kubernetes custom resources provide a powerful means of extending the built-in functionality of Kubernetes. In this course, you will learn how you can use custom resources to tailor Kubernetes to the needs of your application and organization.

Kubernetes comes with out-of-the-box support for most organizational needs via its built-in resources like pods and deployments. But what about those organizations that want to tailor Kubernetes to the specific needs of an application or need a little more customization? For this sort of problem, Kubernetes custom resources are the solution. In this course, Creating Custom Resources in Kubernetes, you’ll learn how to create and use custom resources in order to extend built-in Kubernetes functionality. First, you’ll explore custom resources and custom resource definitions. Next, you’ll discover custom controllers and how you can write your own custom controllers in order to set the state of a running Kubernetes cluster. Finally, you’ll learn how to write your own custom operators and schedulers in order to tailor Kubernetes to the specific needs of your application. When you’re finished with this course, you’ll have the skills and knowledge of custom resources needed to extend and customize Kubernetes.

Extending kubernetes with custom resources

According to students, 'Creating Custom Resources in Kubernetes 1' offers a powerful and practical deep dive into extending Kubernetes. Learners praise its clear explanations of complex topics like Custom Resource Definitions, Controllers, Operators, and Schedulers. The course is highly valued for its relevant hands-on labs and real-world examples, providing immense practical application. However, prospective learners should be aware that it demands significant prior Kubernetes and Go programming experience; some found the prerequisites understated, leading to a steep learning curve. While the instructor's expertise is highly regarded, a few noted that the pacing can be inconsistent and labs might require minor troubleshooting. It's ideal for experienced practitioners seeking to deepen their K8s customization skills.

Provides highly relevant hands-on exercises and demos.

"The hands-on labs were challenging but provided immense practical value."

"The practical examples are excellent and helped solidify understanding. Overall, I learned a lot."

"I gained a lot from the real-world examples and the hands-on practice. Highly recommend to anyone serious about K8s development."

Demystifies advanced Kubernetes concepts effectively.

"The explanations of Custom Resource Definitions and Controllers were incredibly clear, even for someone who knew basic K8s but not the advanced concepts."

"It demystifies Custom Resources, Controllers, Operators, and Schedulers."

"This course provided exactly what I needed to understand Custom Resources. The explanations were clear, concise, and the practical demonstrations were top-notch."

Occasional inconsistencies in pace and minor lab issues noted.

"My only minor gripe is that some parts felt a bit rushed, especially the initial setup, which could be tricky for those not already well-versed..."

"I found myself re-watching sections frequently because the pace was inconsistent."

"There were a couple of instances where the code examples needed slight adjustments due to API changes, but nothing major."

Requires strong prior Kubernetes and Go programming expertise.

"I found it quite challenging without a very strong existing background in Go programming and deep Kubernetes internals."

"This course is not for total beginners; you definitely need a good grasp of Kubernetes and some programming experience."

"I struggled a lot with this course. The prerequisites were not clear enough."

"The assumed knowledge level felt very high; I wish there were more explicit warnings about the required prerequisites, especially for Go."
